账号登录成功，您需要创建应用才可正式调用AI能力。应用是您调用API服务的基本操作单元，您可以基于应用创建成功后获取的API Key及Secret Key，进行接口调用操作，及相关配置。

第一步：去百度智能云注册账号登录：链接：百度智能云-登录 (baidu.com)

第二步：找到右侧顶部蓝色三条杠点击-->产品服务-->人工智能-->人脸识别

第三步：按照首页概括操作

关于创建应用教程：

第四步创建好后保留以下三个字段

AppID	API Key	Secret Key

废话不多说直接上代码

1.创建一个spring boot项目

2.导入maven依赖

    com.baidu.aip    java-sdk    4.16.7

3.创建数据库，如下图所示

4.配置yml

baidu:  appId: 刚刚创建号应用保存的appId  key: 刚刚创建号应用保存的key  secret: 刚刚创建号应用保存的secret

如图所示：

import com.baidu.aip.face.AipFace;import org.springframework.beans.factory.annotation.Value;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.Configuration;@Configurationpublic class BaiduConfig {    @Value("${baidu.appId}")    private String appId;    @Value("${baidu.key}")    private String key;    @Value("${baidu.secret}")    private String secret;    @Bean    public AipFace aipFace(){ return new AipFace(appId,key,secret);    }}
